UNA PROPUESTA CONSISTENTE


UNA PROPUESTA CONSISTENTE


Seis hombres ciegos del Indostán

a los que les gustaba estudiar

fueron a ver a un elefante.

Y, como no lo podían avistar,

se pusieron a tocar y a intentar adivinar.

El primero se aproximó

y, palpándole el flanco al bicho,

acto seguido exclamó:

"Oh, Dios mio, ¿qué es esto que cincho?

Ah, ya se, ¡es como un muro!

estoy casi seguro".

El segundo, haciendo de un colmillo presa,

raudo declaró sin duda:

"redondo,largo y de punta,

no me asusta decir de esa

que es como una lanza o como una vara de yunta."

El tercero se acercó

y puso manos a la obra.

La larga trompa palpó

y con certeza declaró:

"Sin duda y sin zozobra

declaro que es como una cobra".

El cuarto hombre abrazó del elefante una pata,

y palpando la zona del medio

aseguró de forma inexacta:

"¡el elefante es como un madero

y con diez se hace un velero!"

El quinto hombre, al tocar del animal la oreja,

con ojos risueños de chico

aseguro con sabiduría vieja:

"¡es plano como un abanico

y da más aire que una abeja!"

El sexto hombre agarró del enorme bicho el rabo

y sin mas pensar declaró:

"ya se, misterio acabado,

el elefante es como un nabo.

No importa visto de qué lado".

Y he aquí la moraleja amigos,

pues aquellos seis hombres ciegos

a pensar de tener razón en parte

no tenían, en realidad,

el arte de oir más allá de sus propios gorjeos

John Godfrey Saxe 1816-1887

DIÁLOGO CONTROLADOAnalyst: Good morning. With this interview, we aim to clarify the information

concerning the problem domain in which we will work. Please answer the questions in the clearest way possible.

Stakeholder: O.k. Let’s start.

Analyst: What is the name of this organization?

Stakeholder: ZenPhoto™.

Analyst: Please, list the internal/external actors linked to the activities of your organization.

Stakeholder: We have administrators and users.

Analyst: Who can play the role of a user?

Stakeholder: An administrator.

Analyst: Would you please mention some characteristics of users?

Stakeholder: They have custom_data, pass, name, e-mail, right, name_user, valid, group, access, and id.


DIÁLOGO CONTROLADOAnalyst: Please list the main functions of the users.

Stakeholder: He/she uploads and deletes files; publishes albums and uploads images; creates, edits, deletes, and unpublishes albums; enables and disables comments; assigns tags; resets hitcounters; adds, renames, and deletes tags; deletes, approves, disapproves, and edits comments; edits and deletes images; adds comments.

Analyst: Are these functions gathered in some sort of responsibility?

Stakeholder: Yes. Uploads and deletes files are gathered as “edits files;” publishes albums and uploads images are gathered as “creates galleries;” creates, edits, deletes, and unpublishes albums, enables and disables comments, assigns tags, and resets hitcounters are gathered as “manages albums;” adds, renames, and deletes tags are gathered as “edits tags;” deletes, approves, disapproves, and edits comments are gathered as “manages comments;” edits and deletes images edits and deletes images, enables and disables comments, assigns tags, and resets hitcounters are gathered as “manages images;” creates, edits, and deletes users are gathered as “manages users.”


DIÁLOGO CONTROLADOAnalyst: Would you please mention some features of the files?

Stakeholder: Each file has a readable_status, a writable_status, a file_type, a creation_date, a modification_date, a name, and a file_size.

Analyst: Which objects can we categorize and what is the name of the category?

Stakeholder: Subalbums can be categorized under albums.

Analyst: Which of the mentioned features have features themselves?

Stakeholder: Each right has a permit, a description right, and an id. Each access has a unique user and a unique album.

Analyst: Which values or instances can be associated to which feature?

Stakeholder: Admin, Manage all albums, Albums, Files, Tags, Comments, and Upload are instances of description right.

Analyst: What does the user need in order to accomplish the file edition?

Stakeholder: He just need to have description right=“Admin” and description right=“File.”


DIÁLOGO CONTROLADOAnalyst: Would you please establish some sort of sequence in the functions and

responsibilities you have just described?

Stakeholder: In the file editing, the user first uploads the file and then deletes the file; in the gallery creation, the user first uploads the image and then publishes the album; in the album management, the user first creates the album and then edits and deletes the album; in the tag edition, the user first adds the tag and then renames and deletes the tag; in the user management, the administrator first creates the user and then edits and deletes the user.

Analyst: What are the goals and problems associated with the function “creates users”?

Stakeholder: The goals are “increasing the users”, “assuring the access has albums,” and “fostering the permits.” The problems are “access has many restrictions for new users” and “rights are difficult to be granted after a user is created”.

Analyst: Thank you for your valuable information. We will be in contact in order to clarify any doubts that may arise in this process.

Stakeholder: Thank you. I’ll be in touch.

Manages album Responsibility

Even though the word “management” is a noun, the existence of the system leads to the responsibility “manage.”

The amount of users is one of the challenging situations of modern CMS

TextCMS and beyond, page 15

There are few users

Problem

The adjective “few” is implicit in the context, since the “amount of users” as a challenging situation is related to few users.

Some information should be gathered for the images: location, height, width, and owner

We want to foster the usage of files and permits associated with them

Structural triads

Previous interviews with the stakeholder give us the possibility to complement the information based on the image.

Image has size (to be agreed)

Structural triad

Even though there is no explicit size associated with the files in the image, we know that the file needs this attribute.
